Zone Alarm and Windows 10
I'm not able to update my anti-virus and firewall in Zone Alarm. I've tried uninstalling and re-installing and the problem persists. On the MTS website, Windows 10 is not listed under the system requirements for zone Alarm Extreme Security so that's why I wondered if that was the issue.
Not sure if its going to work with the MTS provided license key, but here is the link from Zone alarm to the latest version of Extreme Security that is suppose to work with Win 10.
